Clinton and Fitchburg police, along with State Police investigators assigned to the Worcester County District Attorney's Office, have focused a two-day search on Blueberry Island, a boomerang-shaped patch of land in the middle of Mossy Pond.

Residents on Rogers Field Way told NewsCenter 5 that police had used hovercraft to cross the icy pond and reach the island. Investigators could be seen digging and searching the wooded island with K-9 units.

Police have tried to fly under the radar, but by late Friday word of the search had spread all over town.

"I was wondering what was going on and then somebody told me that they might have found a body, and it's been there something like 20 years," said Clinton resident Marcus Brown.?Resident Matt Notaro drove up to see the search site. "Someone told me that someone's been buried there, someone in prison has admitted to it and it happened a long time ago, about 20 years ago."?Resident Danielle LaJoie said the police search has lit up Facebook and other social media sites.

Many residents are wondering if police might finally find the remains of murder victim Kevin Harkins.

Harkins was killed in 1994, lured out of a Worcester County bar and shot dead because he had reneged on a promise to an acquaintance that he would provide false testimony in a drug case.

Three men were eventually charged in Harkins' murder, but his body was never found.?The Worcester County District Attorney's Office won't comment on what police are looking for or whether they've found anything.

Residents said they saw what appeared to be evidence bags being carried from the island.

"It's a little disturbing, scary, definitely scary," said LaJoie.

Authorities did issue a statement saying the public is not in any danger.

A maid who cleaned the home of former New England Patriots player Aaron Hernandez has testified at his murder trial that she saw him "messing with" the security camera in his basement the day after the killing.
